Availability Zones in vSphere

This topic describes availability zones (AZs) in vSphere and an example of how an operator might scale an app across AZs.

Overview

Pivotal defines an AZ as an operator-assigned, functionally-independent segment of network infrastructure. In cases of partial infrastructure failure, a tile distributes and balances all instances of running apps across remaining AZs. Strategic use of Availability Zones contributes to the fault tolerance and high availability of a tile deployment.
